This standard is published in two parts. Other part is: Part 1 Requirements and test methods for snowboards without inserts The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following: a) Wherever the words `International Standard' appear referring to this standard, they should be read as `Indian Standard'. b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker. In this adopted standard, reference appears to the following International Standard for which Indian Standard also exists. The corresponding Indian Standard which is to be substituted in its place is listed below along with its degree of equivalence for the edition indicated: International Standard ISO 68-1 : 1998 ISO general purpose screw threads -- Basic profile -- Part1 : Metric screw threads Corresponding Indian Standard IS 4218 (Part 1) : 2001 ISO general purpose metric screw threads: Part 1 Basic profiles ( second revision) Degree of Equivalence Identical For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 `Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. IS 15843 (Part 2) : 2012 ISO 10958-2 : 2004 Indian Standard SNOWBOARDS -- BINDING MOUNTING AREA PART 2 REQUIREMENTS AND TEST METHODS FOR SNOWBOARDS WITH INSERTS 1 Scope This part of ISO 10958 specifies requirements and test methods for snowboards on which bindings are attached by means of inserts that are not removable and screws. This part of ISO 10958 does not apply to snowboards for children with a mass less then 25 kg. It contains data for the manufacturer of snowboards, bindings and retention devices concerning dimensions, tests and other specifications for the binding mounting area. For dimensions with no tolerance indicated, a tolerance of ± 1 mm is valid. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 68-1:1998, ISO general purpose screw threads -- Basic profile -- Part 1: Metric screw threads 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 68-1 and the following apply. 3.1 insert reusable commonly threaded attachment point permanently fixed in the snowboard at the time of manufacture, used to mount the bindings to the snowboard and typically arranged in a pattern corresponding to a particular binding manufacturer's pattern 3.2 retention strength axial pull-out force of an insert in a snowboard tested in accordance with 6.1 and 7.1 3.3 spin resistance moment required to rotate an insert tested in accordance with 6.2 and 7.2 1 IS 15843 (Part 2) : 2012 ISO 10958-2 : 2004 3.4 screw thread engagement E number of threads engaged by a standard screw in an insert See Figure 1. 3.5 insert well depth i distance within the insert well from the snowboard top surface to the unobstructed bottom clearance of the binding-insert See Figure 1. 3.6 countersink depth c distance from the snowboard top surface to the first thread of the insert See Figure 1. Figure 1 -- Illustration of screw thread engagement, insert well depth and countersink depth 4 Specifications for design of snowboard insert 4.1 Inserts shall have an M6x1, 6H class internal thread with standard tolerances in accordance with ISO 68-1. 4.2 Insert screws shall have an M6x1, 6g class external thread with standard tolerances in accordance with ISO 68-1. 4.3 The snowboard design shall provide, for a minimum insert well depth i of 5,5 mm, a minimum screw engagement E of 2,0 threads. The length of the screw shall allow a gap between the end of the screw and the bottom of the insert. The effective threaded depth of the insert shall be at least 5,5 mm. The value of 2 threads has been verified by extensive tests carried out by snowboard manufacturers. It is recommended that self-locking screws are used. 4.4 The maximum countersink depth c shall be 2,5 mm. 2 IS 15843 (Part 2) : 2012 ISO 10958-2 : 2004 5 5.1 Strength requirements Retention strength When tested in accordance with 7.1, inserts in a snowboard shall have a minimum retention strength of 4 500 N for those snowboards with a suggested rider mass of 45 kg or more; and a minimum retention strength of 3 500 N for those snowboards with a suggested rider mass between 25 kg and 45 kg. 5.2 Spin resistance When tested in accordance with 7.2, inserts in a snowboard shall have a minimum spin resistance of 20 N·m. 6 6.1 Test apparatus Retention-strength test apparatus Universal test machine (UTM), with a pull-out device according to Figure 2, having a minimum load range of 10 000 N. Dimensions in millimetres Figure 2 -- Universal test machine with pull-out device The pull-out device (see Figure 2) shall consist of a) b) c) a rigid steel attachment plate (A) with one hole of diameter 6,5 mm, a universal joint (B) which is connected to the attachment plate and to the clamping device of the test machine, and a snowboard support (C) with two support rollers with a distance of 200 mm between them. 3 IS 15843 (Part 2) : 2012 ISO 10958-2 : 2004 6.2 6.2.1 6.2.2 6.2.3 Spin resistance test apparatus Device, capable of applying a torque directly to the insert (e.g. long screw with counter-nut).
